Give three examples of the range of variation that you can see in life from around you
(A) Variation in their size - In our surroundings, some organisms are very small in their size as we cannot see them with our naked eyes such as microorganisms whereas some organisms are very big in their size such as blue whales. (B) Variation in a number of cells or cell type - Some organisms have single cells which perform all the functions. These are known as prokaryotic cells such as bacteria. On the other hand, there are some organisms that have organized cells into tissues, organs, organs systems. These are known as eukaryotic cells such as human beings. (C)Variation in the mode of nutrition - Plants make their own food and are hence known as autotrophs. While some organisms depend on other organisms for the purpose of food and are known as heterotrophs.
